What does autonomous driving level L0 mean?

[JuneAnn]

Autonomous driving level L0 refers to driving operations that are entirely performed by the driver. The Society of Automotive Engineers (SAE) has established a classification standard for autonomous driving technology, which includes five levels beyond L0: L1, L2, L3, L4, and L5. L1: Driver assistance, which assists the driver in completing certain driving tasks, but can only assist with one driving operation at a time. The driver must monitor the driving environment and be prepared to take over at any moment. L2: Partial automation, capable of automatically performing both acceleration/deceleration and steering operations simultaneously. L3: Conditional automation, where the vehicle can perform acceleration/deceleration and steering automatically in specific environments without driver intervention. However, the driver must remain attentive and ready to take control of the vehicle at any time. L4: High automation, where the vehicle can operate without any driver input under restricted conditions and within relatively fixed driving areas. L5: Full automation, capable of completely adaptive driving in any driving environment.
